M0

M0 is modular stablecoin infrastructure that lets organizations launch and manage their own custom stablecoins instead of adopting a one-size-fits-all token. Its stack has three independent layers: an application layer for token behavior, rewards, and access controls; a distribution layer for cross-chain liquidity routing; and an issuance layer where teams pick an issuer or become their own. M0 is backed by U.S. Treasury Bill collateral held in special purpose vehicles, and exposes an Orchestration REST API (quotes, cross-chain orders, EIP-2612 permits) plus a Protocol GraphQL API for on-chain data, along with an MCP server and agent skills for AI builders. Used by MetaMask, PayPal, Anchorage, MoonPay, and others.

M0 publishes 4 APIs on the APIs.io network, including Order API, Permit API, Quote API, and 1 more. Tagged areas include Company, Crypto, Stablecoins, Payments, and Blockchain.

M0’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, support, authentication, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/m0: open an issue to ask a question, or submit a pull request to add artifacts.
